Buyer’s Guide: What to Consider

Choosing the best supercharger for your small block Chevy involves more than just picking a shiny blower. You need to consider engine compatibility, kit completeness, build quality, and supporting modifications. This buying guide covers key factors to help you make an informed decision, whether you’re building a street cruiser or a track weapon.

• Engine Compatibility: Ensure the supercharger kit matches your engine’s make, model, and deck height. Small block Chevy (SBC) kits fit 265-400 cubic inch engines, while big block Chevy (BBC) kits fit 396-502. Verify your engine’s rotating assembly is strong enough for boost—forged pistons and rods are recommended for sustained race use.
• Kit Completeness: A complete bolt-on kit includes the supercharger, intake manifold, pulleys, belt, gaskets, and carb adapter. This saves you time and ensures compatibility. Some kits, like the CVF Racing serpentine system, are accessory drives and require a separate supercharger. Decide if you want a full kit or individual components.
• Horsepower Gain: Most Roots-style superchargers add 45-55% horsepower, but actual gains depend on your engine’s base power, boost level, and tuning. Look for kits that specify streetable boost levels. For daily driving, a moderate 6-71 blower is ideal; race setups may need more aggressive boost.
• Build Quality and Durability: Look for heavy-duty bearing plates, double-pinned rotors, and quality seals. These features prevent failure under high RPM and detonation. Brands like Speedmaster and ATI offer warranties (12 months to lifetime) that indicate confidence in their products. Avoid cheap kits with thin castings.
• Installation Requirements: Most kits are bolt-on, but you’ll need mechanical skills and tools. Check if the kit includes all gaskets and hardware. Some require modifications like notching the hood for clearance. Also, factor in the need for upgraded fuel system, carburetor, and ignition components, which are often sold separately.
• Accessory Drive System: A supercharger puts extra load on the serpentine belt system. Upgraded pulleys and a high-grip belt (like an 8-rib design) prevent slipping. The CVF Racing system is a great example of a dedicated drive setup. Ensure your existing belt system can handle the additional power draw.
• Harmonic Damping: Forced induction increases crankshaft torsional vibrations, which can damage bearings and the crank. A harmonic damper (like ATI’s Super Damper) is a critical upgrade. It absorbs vibrations and extends engine life. Don’t skip this if you plan to run high boost levels.

Conclusion

Adding a supercharger to your small block Chevy is one of the most rewarding upgrades you can make, delivering instant power and that iconic whine. The Speedmaster Complete 6-71 Roots kit is our top recommendation for a complete, bolt-on solution that gives you 45-55% more horsepower with minimal hassle. For those needing a serpentine system or harmonic damper, CVF Racing and ATI offer excellent supporting components.

Remember to plan your entire build—including fuel system, carburetion, and engine internals—to handle the increased stress. Whether you choose a full kit or individual parts, investing in quality components ensures your supercharged SBC will be reliable and thrilling for years to come. Now, get out there and start building your dream engine!
